Ratings do not work that way.There will be a curiosity factor for the first few shows, but I doubt it lasts longer than a week. Then he'll be in the same boat Conan was in.
I'm betting it only lasts for the first show.
I've been tempted to leave my cable box on and tuned to CBS if I don't stay up to watch Letterman so he gets another +1 on his ratings even if I'm not actually watching.
Hmmm. Someone told me who works in marketing that the cable companies can tell what channel you are watching and report that back to whoever to determine ratings. Was I (they) misinformed?
